DUST TRUNK OR rues FOR COTTON-OPENERS.

SPECIFICATION forming part of Letters Tatent N 0. 644,975, dated March 6, 1900.

Application filed September 24, 1897. Serial No. 652,933. (No model.)

To all whom it may concern: Be it known that I, WALTER FROsT, a sub ject of the Queen of GreatBritain, residing at Manchester, in the county of Lancaster, Eng

land, have invented certain new and useful Improvements in Dust Trunks or Tubes for Cotton-Openers, of which the following is a specification;

This invention relatesto the pneumatic dust trunks or tubes through which the cotton is carried to theopen-ing-machine from the mixing-room to'ren'der them more efficient and more easily cleaned. It will be fully described with reference to the accompanying drawings.

Figure 1 is a longitudinal elevation of pneumatic dust trunk partly open and partly closed; Fig. 2, a transverse sectional elevation on line Fig. 1; Fig.3, a side eleva tion of division-plate or partitions B; Fig. 4, a side elevation of modified form of divisionplate; Fig. 5, a sectional detail showing fastening for lid or cover D.

In the pneumatic tube or trunk A the grids which catch or separate the dust are formed of a number of loose removable divisionplates or partitions I), that can be readily moved or displaced to allow of the removal of any dirt or fiber that may have accumulated or stuck between them or in the tube..

To each side of the trunk A are affixed brackets C by bolts 0' or otherwise, by which the division-plates B are held preferably suspended in posit-ion.

erably made of the contour shown in Figs. 2

The plates B are prefand 3, with a notch bout at one side and a projection I) at the other to rest upon the supporting-brackets 0, thus suspending the plates as on apivot from a point a little below the top edge. This will allow of the bottom edges being moved to and fro or of a single plate being removed. The division-plates may be otherwise supported each loosely and separately in any convenient manner.

The bottom and one side of the trunk A are made or joined together to form a lid or cover D of angularshape, as shown in Fig.

2, or curved, so as to cover both the bottom and one side of the trunk A. This lid is September, 1897.

hinged orpivoted at the back of the trunk on a pin cl and opens clear of the divisionplates. When the lid D is opened, the bottom and one side of the partition-plates Blare exposed, which allows the loose dirt to fall I a I away and renders the plates easily accessible both in front and beneath for the removal of any dirt or dust adhering thereto. The lid outwith a hole orpassage B of circular or t I other shape through them to give a rubbingsurface both at the top and bottom. (See Fig. 4.)

What I claim as my invention, and desire to protect by Letters Patent, is'

l. A pneumatic dust tube or trunk forsepzu rating dust from fibers, a casing comprising a trunk-casing A, loose division=plates B sus= pended therein, brackets 0 upon which the division-plates are suspended, and a pivoted lid or cover of angular form, inclosing the bottom and one side of the-trunk,- substantiall y as and for the purpose described. I

2. In apneumatic dust tube or trunk for separating dust from cotton fibers, a casing, a number of division-plates constructed with an aperture B to provide a rubbing-surface both top and bottom, in combination-with brackets affixed to the sides of the trunk upon which they are suspended and a pivoted lid or cover to close the bottom and side of the trunk, substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 13th day of WALTER ERosT.
